Features:
1. Regenerative design, using a common DC bus topology, energy conversion between DC channels can be achieved. And, battery discharge energy is preferentially regenerated between DC channels.
2. Regenerative design, if the DC channels cannot be balanced, the extra battery discharge energy will be regenerated to the AC power grid, which saves power and test costs.
3. The power control scheme of DSP&IGBT is adopted to achieve high-speed and high-precision control of electric energy.
4. The margin and timely power control algorithm ensures the stable and reliable operation of battery charger and discharger.
5. The output voltage range, current range, and power range can be freely set, and it is compatible with battery packs of various specifications and models.
6. AC input adopts adaptive technology and does not need to distinguish the phase sequence of the AC power grid.
7. Advanced software phase locking control technology, THD≤5%.
8. Scan the QR code to automatically bind the test process file, and scan the QR code to automatically start testing, avoiding manual errors and improving testing efficiency.
9. Supports automatic judgment of unqualified batteries to improve testing efficiency.
